SWITCH RAIL FOR MONORAIL SUSPENDED RAILWAYS Filed March 9, 1928 PatentedMar. 18, 1930 UNITED STATES OSWALD HAFERKOBN, OF I'OPPITZ, NEARROCHL-ITZ, GERMANY SWITCH RAIL FOR MONORAIL SUSPENDED RAILWAYSApplication filed March 9, 1928, Serial No. 260,405, and in GermanyNovember 22, 1927.

The accompanying drawing illustrates the improved arrangement.

Fig. 1 is a plan view of a railway branch with three switch rails,

Figs. 2 and 3 show the switch rail on a larger scale with the adjoiningtrack rails, in closed and open position respectively,

Fig. 4 is a cross-section through a track rail,

Fig. 5 is a cross-section throu h the switch rail with the operatinghandle thereon,

Fig. 6 is a plan view partly in section of the pivoted attachment of theswitch rail to the track rail.

As shown in Fig. 1, the mono-rail suspended railway comprises in theexample il lustrated a permanent track a and another permanent track dat right angles thereto, with curved branches 6 between them, which areall suspended from a support 0 by means of brackets 79 (Fig. 2), whilebetween the branches 6 and each of the rail tracks a, cl one switch f isarranged, which consists of a rail section. 7

As shown in Figs. 2, 3 and 6, the switch rail f is at one end pivoted atz to fish plates fixed at h to and projecting somewhat from the end ofthe permanent track at and slightly spread apart at their freelyprojecting ends in such a way that the switch rail can be somewhatturned in an upward direction as well as in sidewise directions, while alower abutment n on the end of the permanent track prevents a movementof the switch rail in a downward direction beyond its normal level.

The free end of the switch is at its lower part provided with a notch kcorresponding to a similar notch in the end of the branch rail 6, whichhas lateral fish-plates Z thereon fixed at m and projecting somewhattherefrom to serve as a guide for the free notched end of the switchrail.

The operation of the switch rail is eliected by means of a se aratehandle 0 having a hook p thereon adapted to be placed with its opening 9sidewise over the switch rail, whereupon the latter can be somewhatlifted and changed from one branch rail 6 to the other, or from thepermanent track rail a to the branches 6, as the case may be.

l/Vhat I claim, is:

1. In a switch for mono-rail suspended railways and in combination witha track rail and a branch rail having a free notched end, thearrangement of a switch rail pivoted to the free end of said track railand movable thereon in upward and sidewise directions and having a freenotched end, and means on the said branch rail for guiding the free endof the said switch rail.

2. In a switch for mono-rail suspended railwa s, and in combination witha track rail and a branch rail having a free notched end, thearrangement of a switch rail pivoted to the free end of said track railand movable thereon in upward and sidewise directions, and having a freenotched end, fishplates fixed to the free end of said track railprojecting somewhat therefrom and there spread apart and to which saidswitch rail is pivoted, and an abutment on the track rail for preventingsaid switch rail from moving in downward direction beyond its normallevel.

In testimony whereof I have hereunto set my hand.
